Each day, as the plants rotate, they are periodically watered with a hydroponic growth solution to provide all nutrients necessary for robust growth. Due to the plants continuous fight against gravity, plants typically mature much more quickly than when grown in soil or other traditional hydroponic growing systems. [55]
A wild plant taxon that is closely related to a domesticated plant taxon (e.g. a wild ancestor of the domesticated plant) and which therefore may be indirectly useful to plant breeders by presenting the possibility of introducing genetic material from the wild plant into the domestic relative by crossbreeding. cropdusting
